Yes, NextComputing recommends APC brand UPS/DC power pack bricks. These units usually provide 15–30 minutes of power, depending on your system's configuration.

No, the 810 and 820 series meters operate in using a "single ended supply" meaning you only need between 9 and 25 VDC to operate them. We sell very reasonably priced power supplies that accomplish this in a very economical manner.

No, and external HDD's are not likely to ever be supported as the transfer speed would be too slow to make it worthwhile.

Yes, the Z-Max will automatically detect the power level of both batteries and seamlessly switch between them if necessary. The Z-Max will use the battery with the highest voltage.

Yes, 10-18V DC only. Includes 12V DC battery.What happens if the external supply fails? If the external power fails, batteries must be fitted to prevent loss of data. In the case of a power failure, the logger will switch to the battery supply and continue with no interruption.

The USB bus supplies 0.5 watts minimum and 2.5 watts maximum of power per peripheral. A total of 60 watts maximum power per USB bus.

No- The LCIC board equipped with switching power supply to provide the excitation to the load cells. Just attached the Load cell cable to the board and you are ready.

mA per USB port. See section 7.2.3 for the details of device behavior during suspend and resume. The Device Working Group is working on power management extensions to the common class definition that should alleviate most of the S3 power supply issues with USB. Contact admin@usb.org for more info. In the case of 7.2.4.1, the spec indicates the high power device's configuration can be treated as another hot plug inrush.

The main purpose of your power supply is to run your trains. To run your train your power supply must supply energy for your locomotive, smoke unit, sound system , and any lighted cars. You may also need power for accessories like switches, street lights, building and house lighting or any other accessories. Your TOTAL POWER REQUIREMENTS depends upon the number of locomotives or motors, and ALL OTHER items that require electricity. The length of the track is not a factor.

Yes. Although the Roll-Up II does get some power from the computer, the external power supply is needed to ensure the digitizer has a constant power source. This is especially true if you are using the digitizer with a laptop computer.

Yes. If the Roll-Up III connects via serial port, the external power supply is needed to ensure the digitizer has a constant power source. This is especially true if you are using the digitizer with a laptop computer. The power supply is not needed if the Roll-Up III connects via USB port.

It means powering with USB power through the DC port, not the mini-USB port. It does not matter what is the power source, as long as it is 5v (current output is not too important) and through the DC port. One good example is our dual-purpose cable - PU2MD (PR2MD) - it is a mini-USB sync cable as well as DC power cable. You can charge the player connected to a PC with the DC tip, even with the player battery depleted, with any PC, any OS, or connected to a USB adapter - car or AC.

Yes. There are USB receipt printers, cash drawers and scanners available. If you don't see an interface type you are interested in, please call us.

If not, connect a power supply to the Dock (requires 9 volt, 500 ma, negative center pin) and after it has powered up, retry portable communications. If the Dock does not power up, go to the next question.

In this configuration, your computer thinks that the scanned data is coming from the keyboard. To view the data, simply open any application into which you would normally type, (e.g., a word processor or spreadsheet). Scan the bar code and the data will appear as if it were typed in via the keyboard. My bar code scanner reads the sample codes for Code 39, but will not read the bar codes created with the bar code font on my PC.

Yes, the Z-Max will automatically switch to a suitable external power source without any impact on functionality. The Z-Max will only report capacity information from a battery it can communicate with. The power module is capable of this; power sources input through the external power port are not.

The PoweredUSB specification calls for the following port power minimum capability: (See the PoweredUSB specifications for more detail) VDC: 1.5A RMS with a peak current no greater than 4A for periods of 10ms with a duty cycle of 1/6. Additionally, during power-up, each port should be able to sustain 20A peaks for 100us with a current decay assumed of 20mA/us. VDC: 2.

The USB and Port Security option requires Desktop Authority 7.5. Note that in order to receive technical support for the USB and Port Security option you must update to the latest version of the base Desktop Authority product.
